Mempool Conflict With Multiple Txs in Same Block #4187

Open mrtpain opened 4 years ago

mrtpain commented 4 years ago

Calling multiple smart contracts in the same block from the same wallet often returns txn-mempool-conflict.

Running with Cirrus in Testnet using release/3.0.8.0 branch.

ERROR: Stratis.Bitcoin.Features.SmartContracts.Wallet.SmartContractWalletController.Call Exception occurred: txn-mempool-conflict

To Recreate: Just make 2 contract calls in the same block from the same wallet, more likely than not you'll receive the error. Calls can be creating a contract or calling methods on existing contracts.

Debugging in VS stack trace:
